24.7.x Dashboard slow/not-working Linux laptop; OK WIN 10 laptop -other problems

[NonGough]

1)  A Linux laptop (Debian 12.5, FF ESR browser) fails (often within seconds) after startup of the dashboard widgets (dashboard stops working).  A Windows 10 laptop pressed into duty (old Windows 1709 version, but running the latest Pale Moon and Iridium browsers) runs the dashboard & widgets fine.  The various monitoring OPNsense displays (Live logfile, etc.) sometimes work and sometimes do not even start on the Linux laptop, but always do run on the Windows laptop.
2)  The Linux laptop loses execution focus when the OPNsense provided javascript is interrupted by engaging the screen saver (either by elapsed time or by a manual lock) and then unlocking the screen saver.  The OPNsense javascript never recovers from the screen saver lock on the Linux laptop, but always recovers on the Windows laptop.
3)  Eventually, OPNsense runs out of memory (even when simply running pftop on the OPNsense console of the firewall appliance) after complaining that the swapspace requests have failed - the 10 GB swap space is allocated - and a panic reboot is done.
4) Processing of the Hagezi block lists completed in under an hour in background (pre 24.7).  Does not complete at all starting with 24.7.2 (appears to be related to memory not being freed by OPNsense).  OPNsense is generating every 2-3 minutes a backup configuration file while processing block lists (not just Hagezi).  Disabling Hagezi block list processing has eliminated the generation of hundreds of spurious backup configuration files (which used up 30% of a 500 GB SSD).    24.7.2 is also generating multiple requests to 127.0.0.1:53 (which never occurred pre-24.7.x) when processing block lists - perhaps a surriata <--> OPNsense conflict regarding memory usage and releases.
5)  Memory non-release problems may be related to the Python3 updates . . . . .
In addition, per top running in the OPNsense console shell, Suricata has 297M (increasing about 3M every hour) of resident RAM and 3330M of total  memory when no block lists are being actively processed. The suricata swap footprint goes up when processing blocklists such that eventually even pftop is denied swap space (both 8GB and 10GB max swap sizes have been tried).

The 24.7 dashboard is slow on both Windows 11 (work Lenovo X1 Yoga 3rd) and Fedora 40 (home Dell XPS 14 9440). I normally use Firefox but it's slow on Chrome and Edge also. I haven't tested my MacBook yet.

I have an i9-13900F desktop PC with 96GB of RAM, it's still slow.

I had a similar problem. In my case it was probably due to the "Firewall" and/or "Interface Statistics" widgets. I used all 4 "Reset" buttons under Reporting > Settings and deactivated the widgets. I can't say what the exact solution was, but after that it worked smoothly again.

Testing with both of my Linux/FF ESR and Windows 10/Pale Moon laptops indicates that the OPNsense javascript does not recover when the Screen Saver becomes active either automatically (elapsed time) or manually (lock).  This indicates that the OPNsense's javascript keyboard handler or the javascript interface with the OPNsense appliance server for these situations is problematic (i.e., non-functional).  OPNsense may think that the laptop's running the OPNsense GUI interface have timed out when they have not.
